mediately before the S. I. S., subtract 5
seconds from the rapid advance time and
subtract remainder from the 60 seconds to
determine features time.

These charts show which com-
ponents are energized and should be
functioning during each period of the
program cycle.
REMEMBER:
In addition to the
timer, certain other switches also
control the electrical power supply.
These are:
(1)
the door interlock
switch (2) the over fill control switch,
(3) the program switch and, (4) the
various thermostats and thermal
protectors_
NOTE: On the KDS model, the timer
should be manually advanced ONLY
by removing the dial from the tool
(TL-7213 9) and placing the pointer-
like hub on the timer shaft, then
rotating the hub slowly clockwise to
the desired position. The pointer on
the hub will indicate the cycle phase
in which the timer is operating by
pointing to that portion of the dial
which is already printed on the
surface of the timer_
